Are you comfortable ordering in or cooking a fresh batch of sushi after a hard day at work? However, what if you can’t finish the sushi and want to eat it the next day?
Keeping sushi fresh may seem complicated, but it is not impossible.
Knowing how to store sushi properly is the best way to ensure it stays fresh till the next day. Keep reading to learn how to keep sushi fresh overnight.
How to Keep Sushi Fresh Overnight?
When deciding how to store sushi overnight, you must evaluate the type of sushi you intend to store. For example, whether it is store-bought sushi, restaurant-made sushi, or handmade sushi.
Sushi comprises ingredients such as sashimi (raw fish), Tiger rolls, Tempura rolls, Temaki, Crab, Lobster, Shari (sushi rice), etc.
Unfortunately, most of these ingredients are highly perishable items, so they cannot stay fresh for long periods.
Yet, there are several ways to keep them from going bad for at least 24 hours after cooking.
Here’s how to store the different types of sushi:
- Store-bought: If you have bought packaged sushi from the store, it is best to consume it immediately and not leave it for later since you do not know how long it has been on the store’s shelf. But, if essential, you can store it in a separate container only for a few hours
- Homemade: You can store homemade sushi after cooking in airtight containers, and they will stay fresh overnight
- Sushi ingredients: If you have made separate sushi ingredients, store them in the fright in airtight containers
- Restaurant-made: If you have leftover sushi from the restaurant since it was probably freshly cooked, you may keep it in an airtight container to keep it fresh till the next day
Moreover, if you do not add meat to the sushi and its ingredients are only rice and vegetables, it can stay fresh for up to three to four days.
A prepackaged, sealed sushi container from the market has a life span of two to three days when stored in the refrigerator. The airtight packaging of store-bought sushi containers helps the ingredients stay fresh.
Furthermore, the sauces, dressings, and other ingredients that may be present in the sushi also help maintain the sushi’s consistency and appearance.
Store-bought sushi rice is frequently made using corn syrup and additional preservatives for further preservation.
After you have opened the seal of store-bought sushi, pack it again if you have any leftovers. This is best accomplished by tightly wrapping each sushi roll in saran wrap.
You may refrigerate it after repacking and placing it in an airtight container.
The sushi will rapidly degrade if left out of the refrigerator for an extended period. Additionally, always check the expiry date usually mentioned on store-bought sushi.
Never consume sushi after the expiration date has passed since it may result in illnesses like food poisoning.
Also, never buy room temperature sushi from the grocery store since chilling for food items such as premade sushi is a requirement, according to the FDA (1).
Sushi can be refrigerated for more than 24 hours. However, it’s not the wisest thing to do since it will make the sushi taste bad and become dry, stiff, and hard.
Important Note: Never freeze sushi. Freezing sushi is the worst thing you can do since it will completely ruin the sushi’s quality, taste, and texture and will not taste the same after it is thawed.
Therefore, always keep sushi in the fridge and not the freezer.

Below are a few tips to consider when making your next sushi batch to ensure it stays fresh overnight.

- Cook atthe appropriate temperature and environment
- Know the correct steps
- Have proper tools and utensils
Factors to Consider To Ensure Sushi Stays Fresh Overnight
Here are a few factors you must consider and take care of to ensure your sushi stays fresh overnight.
When keeping sushi overnight, it is critical to examine how long it has been since the sushi was prepared. Eating sushi after more than 24 hours is probably not a good idea.
This is because the perishable ingredients in sushi take minimal time to lose their consistency and freshness if not consumed after 24 hours.
Most restaurants and grocery stores store their sushi in refrigerators or chillers to ensure it stays fresh and no bacteria build up in the raw ingredients.
Suppose you keep sushi at room temperature for more than two-three hours.
In that case, it is best not to freeze it overnight since the ingredients would have already deteriorated enough to make the sushi taste unappetizing.
Moreover, if you live in a hot and humid climate, reduce this time to an hour, as the hotter it is, the quicker the ingredients will go bad, and the faster bacteria will begin to build upon them.
The more time your sushi comes in contact with air, the quicker it will begin to go bad. Your goal is to store it in an airtight container right away.
Adding transparent film to the airtight containers is also great since sometimes air can seep into these containers.
So, once you receive your sushi order or open your store-bought sushi container, the best practice is to take whatever amount of sushi you want to consume and quickly pack it and put it away in the fridge before eating.
Also, remember that if your sushi has been contaminated with water, dust, or anything else, it is best not to store that sushi overnight since these things will make the sushi lose its freshness. Its texture can become hard or soggy.
Since the main ingredients in sushi are raw fish and other seafood items, it requires special care. You can do this by ensuring that everything with which the sushi comes into touch is freshly washed and disinfected.
According to a study, you must avoid using non airtight containers to store raw items since it promotes the build-up of harmful bacteria (2).
So, when storing sushi, do not use dirty tools or non-airtight containers; always wash and dry your containers before putting the sushi in them.
How Can I Determine If Sushi Has Gone Bad?
If you are unsure if your sushi is edible and believe it has gone bad, there are a few signs to check for (3).
- Smell the sushi to see if it tastes bad: If the sushi has a foul or fishy smell, it is not edible, and you must dispose of it immediately
- Check for mold on the sushi container: The sushi has become moldy if you spot any greenish, black, or grey coloring on your sushi. Always check for mold when buying sushi from the store to ensure you don’t bring moldy home sushi. Even the most minor mold on one sushi should be enough for you to throw away the whole box since all sushi rolls would become contaminated even if you cannot see visible signs of mold
- The sushi tastes weird: If you feel a noticeable change in the texture or taste of the sushi, it is best to spit it and throw the leftover sushi away
What Will Happen If I Consume Spoiled Sushi?
Sushi is made out of raw seafood that is more susceptible to being infected with germs and pathogens that can make people unwell from eating them.
Furthermore, if you consume spoiled sushi, you risk contracting Anisakidosis, a gut illness caused by larvae (4).
The most typical signs of foodborne infection include vomiting, diarrhea, stomach cramps, and nausea; however individual symptoms could differ. Therefore, you must talk to a medical health professional if you have these symptoms after eating sushi.
Food poisoning cases can be severe, especially among the elderly, toddlers, pregnant individuals, and those with specific medical problems, who are thought to have a greater risk of complications.
Now that you know how to keep sushi fresh overnight, you can easily store any leftovers without worrying about them going bad.
Use appropriate containers for storage, and don’t leave your uncooked sushi at room temperature for more than two hours.
